IMPROVEDV DiTCHING-MACHINE.

Specification forming part of Letters Patent No. 49,239, dated August 8, 1865.

To all whom it may concern:

Be it known that l, WILLIAM H. DALBEY, of Clarksburg, in the county of Decatur and State of Indiana, have invented a newand Improved Machine for Cutting Drains and Ditches; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, t'orming a part Vot' this specification, in which- Figure lis a side sectional view ,of my invention, taken in the line x w, Fig. 2; Fig. 2, a horizontal section ot' the same, taken in the line y y, Fig. l.

Similar letters of reference indicate like parts. l

This invention relates toa new and improved machine for cutting drains and ditches; and it consists in the employment or use ot' cutters and an elevator arranged with a beam mounted on wheels, as hereinafter fully shown and described, whereby the Work may be done very expeditiously and in a perfect manner.

A represents a beam, to which the team or draft-animals are attached; and B is a yoke,

which is fitted on said beam in such a manner that the latter may ri'se and fall Within it, the sides ofthe yoke iitting in dovetail grooves in sides of the bea-m. The lower part of this yoke has wheels U O attached to it; and D is a screw which passes vertically through the the plate a is fitted to form a connection between the screw and the beam.

E represents a rod, which passes vertically through the beam A, and has a horizontal roller or wheel, F, on its' lower end. l

G is a cutter, which is somewhat inclined from a horizontal position and forms the bot- -tom cut ofthe drain or ditch; and H H are two vertical side cutters, which extend upward from each side of G, the plates of said cutters extending above the beam A and connected at their upper ends by a plate, I, through which a screw, J, passes, the lower end of the latter being connected to the beam in the same way as the screw D of the yoke B.

The plates of the cutters H are tted between guides b at the sides of the beam A.

K represents an inclined box, the lower end of which is attached to the rear of the cutter the earth and insure the rotation of M, from which motion is communicated to the lower` roller, c', of the elevator by gearingf. (Shown in Fig. 1.)

The wheels C C run at each side of the cut,-

and the depth of the latter is regulated by means of the screw D.

Temporary adjustments may be effected through the medium ot' the screw J, in order to admit of the cutters passing over rocks or other obstructions, and also to compensate for the inequalities of surface over `which the wheels C C may pass.

The wheel F serves to prevent any side surging of the machine, as it will come in contact with the sides ot the drain or ditch cut, and the earth cut by the cutters is carried upward by the elevator L, which is made to more with a speed rather faster than the draft movement of the machine, and is discharged through a curved spout, N, to oneV side of the drain or ditch.

The beam A may be of wood; the sides of the elevator-box Kot steel plates, with a hardwood bottom.

The cutters should,o f course, beot' steel but I do not confine myself to any particular ma-l terial for any of the parts.

I claim as new and desire to secure by Letters Patent- 1. The beam A, having the mounted yolteB` applied to it, as shown, in connection with the` WILLIAM H. DALBEY.
